Romans 8:3

For what the law could not do - The law could not pardon; the law could not sanctify; the law could not dispense with its own requisitions; it is the rule of righteousness, and therefore must condemn unrighteousness. This is its unalterable nature. Had there been perfect obedience to its dictates, instead of condemning, it would have applauded and rewarded; but as the flesh, the carnal and rebellious principle, had prevailed, and transgression had taken place, it was rendered weak, inefficient to undo this word of the flesh, and bring the sinner into a state of pardon and acceptance with God.

God sending his own Son in the likeness of sinful flesh - Did that which the law could not do; i.e. purchased pardon for the sinner, and brought every believer into the favor of God. And this is effected by the incarnation of Christ: He, in whom dwelt the fullness of the Godhead bodily, took upon him the likeness of sinful flesh, that is, a human body like ours, but not sinful as ours; and for sin, και περι ἁμαρτιας, and as a Sacrifice for Sin, (this is the sense of the word in a multitude of places), condemned sin in the flesh - condemned that to death and destruction which had condemned us to both.

Condemned sin in the flesh - The design and object of the incarnation and sacrifice of Christ was to condemn sin, to have it executed and destroyed; not to tolerate it as some think, or to render it subservient to the purposes of his grace, as others; but to annihilate its power, guilt, and being in the soul of a believer.

For what the law could not do - The Law of God, the moral law. It could not free from sin and condemnation. This the apostle had fully shown in Romans 7.

In that - Because.

It was weak - It was feeble and inefficacious. It could not accomplish it.

Through the flesh - In consequence of the strength of sin, and of the evil and corrupt desires of the unrenewed heart. The fault was not in the Law, which was good Romans 7:12, but it was owing to the strength of the natural passions and the sinfulness of the unrenewed heart; see Romans 7:7-11, where this influence is fully explained.

God, sending his own Son - That is, God did, or accomplished, that, by sending his Son, which the Law could not do. The word did, or accomplished, it is necessary to understand here, in order to complete the sense.In the likeness of sinful flesh - That is, he so far resembled sinful flesh that he partook of flesh, or the nature of man, but without any of its sinful propensities or desires. It was not human nature; not, as the Docetae taught, human nature in appearance only; but it was human nature Without any of its corruptions.

And for sin - Margin, "By a sacrifice for sin." The expression evidently means, by an Offering for sin, or that he was given as a Sacrifice on account of sin. His being given had respect to sin.Condemned sin in the flesh - The flesh is regarded as the source of sin; Note, Romans 7:18. The flesh being the seat and origin of transgression, the atoning sacrifice was made in the likeness of sinful flesh, that thus he might meet sin, as it were, on its own ground, and destroy it. He may be said to have condemned sin in this manner,

(1) Because the fact that he was given for it, and died on its account, was a condemnation of it. If sin had been approved by God he would not have made an atonement to secure its destruction. The depth and intensity of the woes of Christ on its account show the degree of abhorrence with which it is regarded by God.

(2) the word "condemn" may be used in the sense of destroying, overcoming, or subduing; 2 Peter 2:6, "And turning the cities of Sodom and Gomorrah into ashes, condemned them with an overthrow." In this sense the sacrifice of Christ has no; only condemned sin as being evil, but has weakened its power and destroyed its influence, and will finally annihilate its existence in all who are saved by that death.

(By the sacrifice of Christ, God indeed showed his abhorrence of sin, and secured its final overthrow. It is not, however, of the sanctifying influence of this sacrifice, that the apostle seems here to speak, but of its justifying power. The sense, therefore, is that God passed a judicial sentence on sin, in the person of Christ, on account of which, that has been effected which the Law could not effect, (justification namely). Sin being condemned in the human nature of Christ, cannot be condemned and punished in the persons of those represented by him. They must be justified.

This view gives consistency to the whole passage, from the first verse to the fourth inclusive. The apostle clearly begins with the subject of justification, when, in the first verse, he affirms, that to them who are in Christ Jesus, there is no condemnation. If the question be put, Why is this? the second verse gives for answer, that believers are delivered from the Law as a covenant of works. (See the foregoing supplementary note). If the question again be put, Whence this deliverance? the third verse points to the sacrifice of Christ, which, the fourth verse assures us, was offered with the very design "that the righteousness of the law might be fulfilled in us." This clause, according to the principle of interpretation laid down above, does not relate to the believer's obedience to the righteous requirements of the Law. The apostle has in view a more immediate design of the sacrifice of Christ. The right or demand of the Law δικαίωμα dikaiōma was satisfaction to its injured honor. Its penalty must be borne, as well as its precept obeyed. The sacrifice of Christ answered every claim. And as believers are one with him, the righteousness of the Law has been "fulfilled in them."

The whole passage is thus consistently explained of justification.)

8:3 For what the law - Of Moses. Could not do, in that it was weak through the flesh - Incapable of conquering our evil nature. If it could, God needed not to have sent his own Son in the likeness of sinful flesh - We with our sinful flesh were devoted to death. But God sending his own Son, in the likeness of that flesh, though pure from sin, condemned that sin which was in our flesh; gave sentence, that sin should be destroyed, and the believer wholly delivered from it.
